Permian-Triassic Extinction Event

The Permian-Triassic extinction (or The Great Dying) was the 3rd of mass extinctions on earth, as well as the worst extinction in history. This happened around 253-248 million years ago. This event caused MASSIVE damage to the system of the earth and all animals, both land and sea. It wiped out 95% of all life, on each side. 93-97% of all sea life perished, while 60-70% of land life perished. Trilobites went extinct completely, after existing for nearly 300 million years. This event was so devastating, it took 30 million years for the earth to recover, well into the Triassic Period, and even some into the Jurassic Period. This gave way for the reptiles, and of course, the dinosaurs.
